The Denver Broncos and Seattle Seahawks both held their final pre-Super Bowl practices indoors on Friday.

Well, mostly.

The Seahawks cheated a bit, opening all the doors at the New York Giants' Quest Diagnostic Training Center in East Rutherford to sink the temperature inside, to mimic game-time conditions.

And the Broncos "warmed up" outside, as it were, on an overcast, breezy day before practising indoors at the Jets' Atlantic Health Training Center.

Super Bowl practices always are closed to the media, except for a single pool reporter assigned by the Pro Football Writers Association at each site, who files a report that excludes descriptions of formations and plays.

These reports are distributed to all media covering the game.

"I couldn't ask for more, for the way they've done it," Broncos head coach John Fox said after his team's last practice, 85 minutes in length. "We've been on par. Very focused.

"We talk about the mental preparation. They're going to continue to go through their playbooks, iPads -- whatever information they have -- and continue to review. Now it's mostly just reviewing and visualizing what their job is."

As for the Seahawks, head coach Pete Carroll said of his team's 77-minute practice: "We had a great day today. We finished like I hoped we'd finish, and I thought our execution today was very good."

The pool report said that Seahawks quarterback Russell Wilson "appeared particularly crisp in his execution of the offence and his passes."

Carroll praised his second-year quarterback for his focus and preparation all week.

"And now, we wait," Carroll said.

Both teams plan to hold brief walk-through sessions on Saturday at MetLife Stadium, where Super Bowl XLVIII kicks off the following evening.

FRIDAY'S INJURY REPORT: Once again on Friday, the only player on either team who did not practise was Broncos defensive tackle Sione Fua, with a calf injury. The team officially listed him as doubtful to play on Sunday.

JERSEY BOYS: Unlike the principals in that classic Bruce Springsteen song, there were no meetings across the river for the Broncos or Seahawks.

To hawk radios or otherwise.

Officially, this Super Bowl is hosted by New York and New Jersey.

But neither the Denver Broncos nor Seattle Seahawks as teams ever crossed the Hudson River, all week, from New Jersey into Manhattan.

Both teams were based in Jersey City. The Jets practised in Florham Park, at the Jets' facilities, and the Seahawks up in East Rutherford, at the Giants' practice complex.

That doesn't mean individual players haven't ventured across the river on their own, or in small groups, all week long. For dinner. For sporting events. Or for other socializing, once team obligations ended.

The respective head coaches did hold a joint news conference on Friday morning at Broadway's Rose Theatre -- their first and only functions in Manhattan.

Otherwise, en masse, it's been a 10th Avenue freezeout.

WHO ARE EMERGENCY QBS? Teams usually don't announce who their 'emergency' quarterbacks are.

And do you know who the Denver Broncos' emergency passer is? No? Neither do they, apparently.

Teams normally carry three passers, but usually dress only two on game day. If the starter goes down with injury, the backup goes in.

But if he goes down, then who?

That's the emergency quarterback -- someone at a different position who can take those "emergency" snaps.

Can you remember the last time that happened in an NFL game? Neither can we.

Still, stranger things have happened in a Super Bowl. So we asked players on both teams.
